摘要： In the present invention, when a status of clogging a paper due to some cause occurs, controls of inverting a conveyance roller and returning the jammed paper in a paper feeding tray is performed. At this time, the position of a paper damming up member is lowered by an actuator when the jammed paper is returned to the paper feeding tray and the conveyance roller is inverted so as to avoid a state in which the paper damming up member 33 hinders the returning of the paper and the paper cannot be returned to the paper feeding tray. The paper damming up member is lowered to a position that is lower than a conveyance guide plate at a downstream side in a paper conveying direction. Then, the paper is returned to the paper feeding tray without damage. The returned paper can be reused.

摘要： A sheet feeder, which is included in an image forming apparatus, includes a sheet loader, an air blowing device, a regulator, a sheet attracting device, and a sheet conveying body. The sheet loader loads a sheet bundle including a sheet and a subsequent sheet placed below the sheet. The air blowing device blows air and lifts the sheet over the sheet bundle. The regulator regulates movement of the subsequent sheet, and includes an opposing portion located upper end and separated from the sheet loader toward the downstream side of the sheet conveying direction and an inclined portion upwardly inclined relative to a vertical axis from a same position as the sheet loader to the downstream side of the sheet conveying direction. The sheet attracting device attracts the sheet lifted over the sheet bundle. The sheet conveying body conveys the sheet in a sheet conveying direction.
